BYD are genuinely decent cars. And they've skyrocketed in popularity across parts of the world.
In the UK the major car dealers are franchises, and you tend to see for example a Ford garage next to a Toyota garage, and they are operated by the same company. Most of these places have closed one of the branded ones and turned it into a BYD franchise dealership. Theres so many of them across the country now.
I'd take a BYD over something like a Tesla thats for sure - far better cars, it's not even a fair comparison anymore.
I dare say they'll struggle a little more in the US with the whole "China bad" propaganda engrained into society, which is likely why BYD have gone for the agressive expansion in Europe instead.
